| Abstract: | Objective： To establish a new method of determining sulfur dioxide residue in wine. Method： Sulfur dioxide released from wine by distillation was absorbed with formaldehyde absorption solution, and then determination was conducted by reduction photometry. Results： The use of formaldehyde absorption solution had no effect on the determination of sulfur dioxide. The accuracy test on the method indicated RSD and recovery as 1.9% and 95% - 103%, respectively. Conclusion： Featured by good simplicity, accuracy and repeatability, the method can be applied to the determination of sulfur dioxide residue in wine with satisfactory results. |
